BACKGROUND

1. Field of the Invention

The invention relates to a mounting part for body attachment parts inthe automotive field, such as for example paneling elements, lampcasings for lamp units, etc., having at least one first, body-sidefastening arrangement and having at least one second,attachment-part-side fastening arrangement. The invention also relatesto a mounting arrangement having a mounting part of said type.

2. Description of the Related Art

Mounting parts or mounting arrangements for mounting an attachment to abody are well known in the automotive field. For example, DE 10 2006 015399 A1 discloses a mounting part that is intended to simplify the designmeasures and assembly outlay required for fastening body attachmentparts, such as for example paneling parts or lamp casings.Unfortunately, however, the known mounting parts have the disadvantagethat, with ever more complex structural space concepts, they take up toomuch free space and thus oppose flexible utilization of the structuralspace.

It is therefore an object of the invention to provide a mounting partand a mounting arrangement that eliminate the disadvantage mentionedabove.

SUMMARY OF THE INVENTION

The invention relates to a mounting part with at least one flow crosssection for fluidically connecting the atmosphere to a cooling device.In this way, the mounting part performs the mounting functions for bodyattachment parts and also the function of flow guidance. Thus, thestructural space taken up by the mounting part is utilized in an optimummanner. Sealing elements advantageously are provided for a fluid-tightconnection to a body attachment part and/or to the cooling device. Inthis way, the mounting part is connected to the respective connectedpart in an accurately fitting manner. The mounting part may provideflow-guiding surfaces to ensure efficient flow guidance. Furthermore,fins may be provided in the flow cross section. The fins improve flowthrough the mounting part and significantly increase the rigidity of themounting part.

The mounting part may be formed in one piece and produced from plastic.The fastening arrangement may have at least one receiving slot that canbe placed in operative connection with corresponding web-like extensionpieces of the body attachment parts.

The invention also relates to a mounting arrangement having theabove-described mounting part and a flow grille is provided such thatthe cooling device is fluidically connected to the atmosphere. Thecooling device is particularly advantageously in the form of acharge-air cooler that may be arranged, for example, in the rear end ofa motor vehicle, where installation space may be limited.

The mounting arrangement may comprise a fender paneling part below theflow grille. Further body attachment parts may comprise lamp casings anda faceplate part above the flow grille. The body attachment partsadvantageously have at least one web-like projection that engages intothe corresponding receiving slot of the mounting part.

The invention will be explained in more detail below on the basis of thedrawings.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a perspective view of a rear-end region of a motor vehicle.

FIG. 2 is a sectional view through the rear end from FIG. 1.

FIG. 3 is a partial detail view of the mounting part in the installationsituation of FIG. 2.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 is a perspective view of a rear-end region 2 of a motor vehicle4. The rear-end region 2 has different body attachment parts, such as afender paneling part 6, a lamp casing 8, a flow grille 9 and a faceplatepart 10. The lamp casing 8 and the faceplate part 10 are arranged abovethe flow grille 9, and the fender paneling part 6 is arranged below theflow grille 9.

FIG. 2 is a sectional view through the rear end 2 of the motor vehicle 4of FIG. 1, and will be explained below with reference to FIG. 3. Themotor vehicle 4 has a drive engine (not illustrated) in the rear end 2.The drive engine is connected operatively in a known way to asupercharging device and to a cooling device in the form of a charge-aircooler 11 that is connected to the supercharging device. The dispositionof the drive engine with charge-air cooler 11 in the rear end 2complicates installation space requirements. To utilize the installationspace optimally, a mounting arrangement 12 is provided and has amounting part 13 with body attachment parts 6, 8, 9, 10 connectedthereto. The mounting part 13 is illustrated in most clearly in FIG. 3.

The mounting part 13 has multiple receiving slots 14, 16, 18, 20 thatare assigned different functions. The receiving slot 14 is part of afirst, body-side fastening arrangement 22 that connects the mountingpart 13, and the attachment parts 6, 8, 9, 10 connected thereon to abody 24 of the motor vehicle.

The receiving slot 16 is part of an attachment-part-side, secondfastening arrangement 26 and receives the faceplate 10 by way of aweb-like projection 17 and the lamp casing 8 by way of a web-likeprojection. The receiving slot 18 is part of a furtherattachment-part-side, second fastening arrangement 28 and receives aweb-like projection 21 of the fender paneling part 6. It should be clearthat the body attachment parts 6, 8, 10 mentioned by way of example arefixed in a non-positively locking and/or positively locking manner tothe vehicle 4 after being inserted into the respective receiving slot16, 18.

The mounting part 13 has a flow cross section 30 that functions forfluidic connection of the charge-air cooler 11 to the atmosphere. In thepresent exemplary embodiment, to form the flow cross section, themounting part 13 has fins 32 that function simultaneously as areinforcement for the mounting part 13.

In the present exemplary embodiment, the charge-air cooler 11 hasflow-guiding surfaces 34, 36 that bear sealingly against the mountingpart 13. This is shown by way of example for the flow-guiding surface 34where the end directed toward the mounting part 13 has a sealing element38 that rests sealingly in a further receiving slot 20. As illustratedin FIG. 2, the flow grille 9 is clipped to the fins 32 of the mountingpart 13.

The mounting arrangement of the invention with the mounting part 13ensures in a particularly simple manner that the air exiting thecharge-air cooler 11 is discharged into the atmosphere via the flowcross section 30 of the mounting part 13 and the flow grille 9. Itshould also be clear that the body attachment parts, and in this case,the faceplate part 10 and the flow grille 9, are not subject to anyrestrictions with regard to form and color.
